Important User Information
Solid-state equipment has operational characteristics differing from those of electromechanical
equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls
(Publication SGI-1.1 available from your local Rockwell Automation sales office or online at
http://www.rockwellautomation.com/literature/) describes some important differences between
solid-state equipment and hard-wired electromechanical devices. Because of this difference, and also
because of the wide variety of uses for solid-state equipment, all persons responsible for applying this
equipment must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the
many variables and requirements associated with any particular installation, Rockwell Automation, Inc.
cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits,
equipment, or software described in this manual.

Environment and Enclosure
Preventing Electrostatic Discharge
ATTENTION: This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters without derating.
This equipment is not intended for use in residential environments and may not
provide adequate protection to radio communication services in such
environments.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR Publication 11. Without appropriate precautions, there may be
potential difficulties ensuring electromagnetic compatibility in other
environments due to conducted as well as radiated disturbance.
This equipment is supplied as “open type” equipment. It must be mounted
within an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The interior of the enclosure
must be accessible only by the use of a tool. Subsequent sections of this
publication may contain additional information regarding specific enclosure type
ratings that are required to comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1, for additional installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the
degrees of protection provided by enclosures.
ATTENTION: This equipment is sensitive to electrostatic discharge, which can
cause internal damage and affect normal operation. Follow these guidelines
when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.

ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
The following information applies when
operating this equipment in hazardous
locations:
Informations sur l'utilisation de cet équipement
en environnements dangereux:
Products marked "CL I, DIV 2, GP A, B, C, D" are suitable
for use in Class I Division 2 Groups A, B, C, D, Hazardous
Locations and nonhazardous locations only. Each product
is supplied with markings on the rating nameplate
indicating the hazardous location temperature code.
When combining products within a system, the most
adverse temperature code (lowest "T" number) may be
used to help determine the overall temperature code of
the system. Combinations of equipment in your system
are subject to investigation by the local Authority Having
Jurisdiction at the time of installation.
Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne conviennent
qu'à une utilisation en environnements de Classe I Division 2
Groupes A, B, C, D dangereux et non dangereux. Chaque produit
est livré avec des marquages sur sa plaque d'identification qui
indiquent le code de température pour les environnements
dangereux. Lorsque plusieurs produits sont combinés dans un
système, le code de température le plus défavorable (code de
température le plus faible) peut être utilisé pour déterminer le
code de température global du système. Les combinaisons
d'équipements dans le système sont sujettes à inspection par
les autorités locales qualifiées au moment de l'installation.
EXPLOSION HAZARD
• Do not disconnect equipment unless
power has been removed or the area is
known to be nonhazardous.
• Do not disconnect connections to this
equipment unless power has been
removed or the area is known to be

Install the Module
To install the module on the DIN rail, proceed as follows.
1. Position the module vertically above the DIN rail
2. Press down firmly to install the module on the DIN rail.
The locking mechanism will lock the module to the DIN rail.
3. Remove the safety end cap by sliding it up to expose the backplane and power
interconnections.
ATTENTION: When you insert or remove the module while backplane power is
on, an electrical arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.
ATTENTION: Do not discard the end cap. Use this end cap to cover the exposed
interconnections on the last mounting base on the DIN rail. Failure to do so
could result in equipment damage or injury from electric shock.

Install the Module in an Existing System
To install a replacement module in an existing system, proceed as follows.
1. To remove the module from the DIN rail, pull up on the RTB removal handle to
remove the terminal block.
2. Use a small-bladed screwdriver to rotate the DIN rail locking screw to a vertical
position. This releases the locking mechanism.
3. Lift straight up to remove.
4. Position the module vertically above the DIN rail.
5. Slide the module down so that the interlocking side pieces engage the adjacent
module.
6. Press firmly to seat the module on the DIN rail.
The module locking mechanism will snap into place.
WARNING: When you connect or disconnect the Removable Terminal Block
(RTB) with field side power applied, an electrical arc can occur. This could cause
an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
